JAMES RAVVLE, OF RADNOR, PENNSYLVANIA.

WATER-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 536,738, dated April 2,1895.

- Application filed October 9, 1894. Serial No. 525,366. (No model.)

To aZZ whom it may concern:

Be it known that 1, JAMES RAWLE, a citizen of the United States,residing at Radnor township, in the county of Delaware and State ofPennsylvania, have made certain new and useful Improvements in Water-Sprinklers and the Like, of which the following is a specification.

The object of my invention is to provide a Water sprinkler which will besimple in construction and effective in use, and wherein the nozzle orwater outlet can be readily adjusted to permit the passage of more orless water as desired.

The invention consists in the novel details of construction and thecombinations of parts that will be more fully hereinafter set forth andthen pointed out in the claims. I

Reference is to be had to the accompanying drawings, forming parthereof, wherein- Figure 1 is a side elevation of my improved sprinkler;and Fig. 2 is a central longitudinal section thereof. I

In the accompanying drawings, in which similar letters and numerals ofreference indicate corresponding parts in the several views, the letterA indicates a tube or pipe of suitable dimensions, at one end of whichis fitted an apertured spider B. The spider B may be secured in the tubeA, by screw threads at on the inner wall of said tube fitting intothreads I), on the periphery of said spider, by which means said spideris made adjustable longitudinally of said tube; but the spider B may beotherwise connected with the tube A, if desired. The opposite end of thetubeA may have screw threads 0 to receive any suitable coupling toconnect the tube A with a water supply source.

D is a cone-shaped head or deflector fitting over or in front of thespider B, so that its diverging sides will receive the water from theapertures in the spider B. The cone Dis preferably cast hollow, for thesake of lightness, and its small end or apex D' ezgtends toward andabuts against the spider B, so that its large end will cause the passingwater to spread out. The cone-head D is shown provided with a crown-web2 and alongitudinal aperture (1 d in the web and end D, through which abolt E passes, and screws into a threaded socket e in the spider B.

Atfis a washer between the cone-head D and the head-of the bolt E. Bythis means the cone-shaped head is carried by the tube A withoutanyexternal obstruction to the flow of the water.

The head D at its outer end is provided with a flange F, which isoutwardly curved, and arranged to direct the water in an outwarddirection. This curve may be altered to get the desired direction offlow, if desired. The flange F on top may be inwardly curved, as shown,to save weight of metal.

G is a cap, or reducing nozzle, that fits on the end of the tube A, theouter end of said cap being adapted to coact with the cone like part ofthe head D in producing an annular opening 9 for the exit of water. Thecap G is. shown fitted on the end of the tube A by screw threads h, 2',whereby said cap can be adjusted on said tube to increase or diminishthe size of the opening 9 to permit more or less water to pass. The capG, at the part beyond the tube A, is shown reduced in size or narrowed,forming a curved shoulder 7, against which the water passing from thespider B abuts to break the force of the water and direct it against thecone-head D.- Instead of using the shoulder, the cap could be of agradual taper, if desired.

With the above described arrangement of 1 sprinkler the water issuingfrom the tube A will enter the space Z between the head D and cap G, andwill follow along the walls of said head out through the annular openingg, from whence it will strike the curved flange F, and

be directed outwardly in lines following the curve of said flange.

As the device has few parts it is not liable to get out of order, and issimple and cheap to construct.

2. The combination of a tube havinginternal threads a and externalthreads i, a spider having threads to mesh with the threads (1, acone-like head having a flange F, means to hold said head on saidspider, and a cap having threads to engage the threads h on the tube A,all arranged for operation, substantially as set forth.

3. In a sprinkler,the combination of a tube, a deflector and a reducingcap surrounding the deflector, the cap being adjustable independently ofthe deflector, substantially as described.

at. In asprinkler, the combination'of a tube, a deflector adj ustablysupported therein, and a reducing cap independently adjustable on saidtube, substantially as described.

5. In a sprinkler, the combination of a tube, internally and externallythreaded, a spider peripherally and centrally threaded and screwedwithin said tube, a reducing cap screwed about said tube, and adeflector secured by a screw centrally to said spider, substantially asdescribed.

6. In a sprinkler, the combination, with the tube and a spider securedtherein having a hub e of a deflector having a cylindrical portionadapted to abut against said hub and form a continuation thereof, and aconical or diverging portion extending from the cylindrical portion, andmeans for securing the deflector to the spider, and a cap on the tubesurrounding the deflector and independently movable in relation thereto,substantially as described.

7. The combination with the tube, of the spider therein, the deflectorsecured to the spider and projecting therefrom, and a cap encircling thespider and secured to the tube, said cap having an interior shoulder jfor intercepting the water, substantially as described.

8. In a sprinkler, the combination with the tube, of the spider therein,the deflector secured to the spider, a cap secured to the tube andencircling the deflector, said cap having two diameters, the greaterbeing secured to the tube, the smaller extending over the deflector, anda shoulder j defining the two diameters, substantially as described.

9. In a sprinkler, the combination with the tube, of the spider therein,the deflector extending from the spider, and a cap on the tubesurrounding the deflector and having a space or chamber Z intermediateof its ends, substantially as described.

10. In a sprinkler, the combination with the tube, of the spidertherein, and the hollow conical deflector extending from the spider,having the flaring flange F and the crownweb 2, an apertured hub D, anda headed bolt E passing through the web and hub into the spider,substantially as described.

Signed at Philadelphia, in the county of Philadelphia and State ofPennsylvania, this 31st day of August, 1894:.

JAMES RAWLE.
